The Last Day

The Last Day fleshes out a key moment that is spoken about in snippets in first few years of the show’s return - then fall of Arcadia. It is a genuinely unsettling, low budget short which is perhaps a little too short for the breadth of the ideas they are trying to portray. We do not get enough time to invest in the characters, or build up the anticipation of the final demise. But we do get a good scare.

"Nothing could possibly go wrong!"

Prerequisites: Nothing explicit, but I'd recommend watching this paired with the other 50th Anniversary episodes.

The Last Day isn't a bad minisode, but it is admittedly very short and fairly cheap. The ideas are cool; I like the concept of these 'premonitions', and the headcam perspective was novel. The ending, while predictable, is effective, and it all makes for a fairly decent introduction to The Day of the Doctor.
